15. A magnetic field B= 0.6T is directed upward through a circular loop of diameter 7 cm and 500 turns. The loop is initially horizontal, so it is perpendicular to the magnetic field. It rotates through a horizontal axis so that the plane of the loop is at 74° with the horizontal axis within 1 second. What is the magnitude of the induced emf? A. -15.3 V В. 17.6 V C. 16.4 V D. -18.18 V 16. Which of the following color has the longest wavelength? A. yellow 17. What will be the arrangement of electromagnetic waves if we will arrange them according to decreasing energy? В. red C. blue D. green B. X-ray, gamma, ultraviolet D. Gamma, ultraviolet, X-ray A. Gamma, radio, microwave C. X-ray, light, radio
